A large balloon has been tied with a rope and it is floating in the air. A person has observed the balloon from the top of a building at angle of elevation of theta_1 and foot of the rope at an angle of depression of theta_2 . The height of the building is h feet. Draw the diagram for this data.

The organ 'A' of a person has been damaged completely due to a poisonous waste material 'B' has started accumulation in his blood, making it dirty. In order to save this person's life, the blood from an artery in the person's arm is made to Dow into long tubes made of substance 'E' which are kept in coiled form in a tank containing solution 'F'. This solution contains three materials 'G', 'H' and 'I' and similar proportions to those in normal blood. As the person's blood passes through-long tubes of substance 'E', most of the wastes present in it go into solution 'F'. The clean blood is then put back into a vein in the person for circulation. What is the process described above known as ?

Read the passage People started trapping, posoning and killing sparrow s in large numbers.Several free fire zones were set up for shooting the sparrows. People would beat drums to scare the birds from landing, so the sparrow ere forced to keep glying until they dropped dead from fatigue. Sparrow nests were torn down, egges were broken and nesttling were killed .Non material rewardsand recoginition were offered to school, work uits and gvernment agencies in accrdance with the number of sparrows killed . Later some scientists who cut open the digestive system of deal sparrows found that three- fourth of the contents were of insects harmful for crops adn ony one fourth contained grains. The scientiffic findings showed that sparrow were basically beneficial birds for humans. Rather than being increased, crop yields after the campaign were substantially decreased. What is the reason for less yield in the fields ?

Answer carefully: (a) Two large conducting spheres carrying charges Q_(1) and Q_(2) are brought close to each other. Is the magnitude of electrostatic force between them exactly given by Q_(1),Q_(2)//4pi epsilon_(0)r^(2) , where r is the distance between their centres? (b) If Coulomb’s law involved 1//r^(3) dependence (instead of would Gauss’s law be still true ? (c) A small test charge is released at rest at a point in an electrostatic field configuration. Will it travel along the field line passing through that point? (d) What is the work done by the field of a nucleus in a complete circular orbit of the electron? What if the orbit is elliptical? (e) We know that electric field is discontinuous across the surface of a charged conductor. Is electric potential also discontinuous there? (f) What meaning would you give to the capacitance of a single conductor? (g) Guess a possible reason why water has a much greater dielectric constant (= 80) than say, mica (= 6).
